For patients with kidney stones who have painful symptoms, if the pain is still present after applying painkillers, it is possible that the stone is stuck in the ureter, causing persistent renal colic. If the renal pelvis is separated by more than 2 cm, it means that the obstruction pressure is relatively large and the kidney function has been damaged, so extracorporeal shock wave lithotripsy or holmium laser lithotripsy should be performed urgently. After lithotripsy, it is important to drink enough water, 2000-2500ml per day, and to perform longitudinal exercise to observe the discharge of stones. If the symptoms of fluid accumulation are relieved and there is no significant back pain, the stone is fully discharged.
